If given the equation
y = 3(x + 5)² - 4,
what is the vertex of the parabola?

• (5, -4)
• (-5, -4)
• (-15, -4)
• (15, -4)

Identify a, h, k: f ( x ) = 5 ( x - 4 ) ² + 3

• a = 5, h = -4 , k = 3

• a = 5, h = 4 , k = 3

• a = 5, h = -4 , k = -3

• a = 5, h = 4 , k = -3

What is the vertex of this parabola?

• (−1, 3)

• (−3, 11)

• (−2, 5)

• (0, 5)

Which of the following functions shows an initial amount of $15 and an increase of 35% each year?

• y = 15(35)^x
• y = 15(1.35)^x
• y = 15(0.35)^x
• y = 35(1.15)^x
